Where relevant (for example for users residing in the European Union), BIG DG also takes into account the principles of the General Data Protection Regulation (GDPR), particularly regarding individual rights and international data transfers.

  • Commercial or technical partners when necessary for a specific service.
  • Competent administrative or judicial authorities when required by law or to defend the rights of BIG DG or third parties.

11. Hosting and International Data Transfers

Rails App Services may be hosted on servers located in Tunisia or in other countries (for example in the European Union or other jurisdictions), depending on the chosen service providers.

13. Data Security

BIG DG implements reasonable technical and organizational measures to protect your personal data against accidental or unlawful destruction, loss, alteration, disclosure, or unauthorized access (access control, encryption of certain data, etc.).

As no system is completely secure, the security of your data also depends on the precautions you take (strong password, not sharing access, protecting your devices).
